DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0033] As described in the background, with the development of vehicle light illumination technology, the light emitting structure for vehicle light not only shows charm in illumination and signal light functions, but also plays a role in display functions. And with the universal application of the light emitting structure in display components, users have higher and higher requirements for the uniformity of the light color of the light emitting structure. However, the existing light emitting structure has serious color dispersion when mixing light, so the light emitting structure needs to be improved.

[0034] Based on this, the embodiment of the present application provides a light emitting structure, a light emitting device and a vehicle, effectively solving the technical problems existing in the prior art, by setting the anti-dispersion part on the light entrance surface of the inner lens, to improve the dispersion problem of different color light emitted by the light source when passing through the inner lens, improve the light mixing effect of the light emitting structure, and improve the light color uniformity of the light emitting structure.

[0035] To achieve the above object, the technical scheme provided by the embodiment of the present application is as follows, which will be described in detail in combination with Figures 1 to 7 The technical scheme provided by the embodiment of the present application is described in detail.

[0036] Reference Figure 1 The structure of the light emitting structure provided by the embodiment of the present application is shown in the figure, wherein the light emitting structure provided by the embodiment of the present application comprises: an inner lens 100, the light entrance surface 110 of the inner lens 100 comprises an anti-dispersion part 111 and a light entrance part 112 arranged in the first direction X; a light source 200, the light source 200 is arranged on one side of the light entrance surface 110 of the inner lens 100, and the light source 200 is arranged opposite to the light entrance part 112; wherein the light source 200 comprises at least two light emitting elements 210, the light emitting element 210 is arranged opposite to the light entrance part 112, and the light emitting color of at least one light emitting element 210 is different from that of the remaining light emitting elements 210.

[0037] From the above content, it can be known that when the light emitting structure realizes the light mixing effect, at least part of the light emitting elements 210 with different light emitting colors in the light source 200 will emit corresponding light to the inner lens 100. Since the light entrance surface 110 of the inner lens 100 of the light emitting structure is provided with the anti-dispersion part 111, when different color light enters the inner lens 100 through the light entrance surface 110, it will be emitted after optimized light mixing by the anti-dispersion part 111, thereby improving the dispersion problem of different color light emitted by the light source 200 when passing through the inner lens 100, improving the light mixing effect of the light emitting structure, and improving the light color uniformity of the light emitting structure. In addition, when the light emitting structure realizes monochromatic light emission, one light emitting element 210 of the light source 200 is controlled to be lit, or at least part of the light emitting elements 210 with the same light emitting color in the light source 200 are controlled to be lit, when the same color light enters the inner lens 100 through the light entrance surface 110, it will be processed by the anti-dispersion part 111 to ensure the high light color uniformity of the light emitting structure.

[0038] It is understandable that in the light source 200 provided in the embodiment of the present application, when the light source 200 is controlled to emit light, each light-emitting element 210 can be controlled to light up individually; or some of the light-emitting elements 210 can also be controlled to light up at the same time, wherein the light-emitting colors of the light-emitting elements 210 that are controlled to light up at the same time can be the same, or at least one of the light-emitting colors of the light-emitting elements 210 that are controlled to light up at the same time can be different from the light-emitting colors of the remaining light-emitting elements 210; or all of the light-emitting elements 210 can be controlled to light up at the same time, and this application does not impose specific restrictions on this lighting control method. In some embodiments, when controlling the light-emitting structure to mix light and emit light, some of the light-emitting elements 210 with different light-emitting colors can be controlled to light up and emit light to the inner lens 100, or all of the light-emitting elements 210 can be controlled to light up and emit light to the inner lens 100. Since the light incident surface 110 of the inner lens 100 provided in the embodiment of the present application is provided with an anti-dispersion portion 111, the anti-dispersion portion 111 can improve the dispersion problem of different colored lights emitted by the light source 200 when passing through the inner lens 100, thereby improving the light mixing effect of the light emitting structure and improving the color uniformity of the light emitted by the light emitting structure. In other embodiments, when the light emitting structure realizes monochromatic light emission, one light emitting element 210 of the light source 200 is controlled to light up, or at least some of the light emitting elements 210 of the same light emitting color in the light source 200 are controlled to light up. When light of the same color enters the inner lens 100 through the light incident surface 110, it will be evenly lighted by the anti-dispersion portion 111 to ensure that the color uniformity of the light emitted by the light emitting structure is high.

[0039] In some embodiments, the anti-dispersion portion 111 provided in the embodiment of the present application can be centrally arranged and located on the same side of the light incident portion 112; Figure 1 As shown, in the first direction X, the anti-dispersion portion 111 is located on the same side of the light entrance portion 112. It can be seen that when the light-emitting structure is required to achieve mixed light emission, the light-emitting elements 210 of different light-emitting colors of the light source 200 are controlled to light up, and the light emitted by the light-emitting element 210 is incident on the interior of the inner lens 100 through the light entrance portion 112 and the anti-dispersion portion 111, and when entering the interior of the inner lens 100 through the anti-dispersion portion 111, the light of different colors will be optimized and mixed to ensure a high light mixing effect of the inner lens 100, improve the light mixing effect of the light-emitting structure, and improve the color uniformity of the light emitted by the light-emitting structure. In addition, when the light-emitting structure achieves monochromatic light emission, when the light of the same color emitted by the light source 200 enters the inner lens 100 through the light entrance surface 110, it will be evenly lighted by the anti-dispersion portion 111 to ensure a high color uniformity of the light emitted by the light-emitting structure.

[0040] Alternatively, in other embodiments, the anti-dispersion portion 111 provided in the embodiment of the present application can also be divided into two parts and respectively located on both sides of the light incident portion 112; Figure 2The figure shows a schematic diagram of the structure of another light-emitting structure provided by an embodiment of the present application, wherein the anti-dispersion portion 111 provided by the embodiment of the present application includes a first sub-anti-dispersion portion 1111 and a second sub-anti-dispersion portion 1112; in the first direction X, the first sub-anti-dispersion portion 1111 and the second sub-anti-dispersion portion 1112 are respectively located on both sides of the light-entering portion 112. It can be seen that when the light-emitting structure is required to achieve mixed light output, the light-emitting elements 210 of different light-emitting colors of the light source 200 are controlled to light up, and the light output of the light-emitting element 210 is incident on the interior of the inner lens 100 through the light-entering portion 112, the first sub-anti-dispersion portion 1111 and the second sub-anti-dispersion portion 1112, and when entering the interior of the inner lens 100 through the first sub-anti-dispersion portion 1111 and the second sub-anti-dispersion portion 1112, the light of different colors will be optimized and mixed to ensure a high light mixing effect of the inner lens 100, improve the light mixing effect of the light-emitting structure, and improve the light color uniformity of the light output of the light-emitting structure. In addition, when the light-emitting structure realizes monochromatic light emission, when the light of the same color emitted by the light source 200 enters the inner lens 100 through the light incident surface 110, it will be evenly treated by the first sub-anti-dispersion part 1111 and the second sub-anti-dispersion part 112 to ensure that the light color of the light emitted by the light-emitting structure is highly uniform.

[0041] Furthermore, the light incident portion 112 of the inner lens 100 provided in the embodiment of the present application may be a light-collecting structure surface. Figure 3 , which is a schematic structural diagram of another light-emitting structure provided in an embodiment of the present application, wherein the light-entering portion 112 provided in the embodiment of the present application is a light-collecting portion. The light-entering portion 112 may be a convex surface, and when the light emitted by the light source 200 is irradiated on the convex surface, it can be collected and transmitted to the interior of the inner lens 100, thereby improving the brightness of the light emitted by the inner lens 100 while ensuring a high light mixing effect and high uniformity of light color of the light emitted by the inner lens 100, thereby improving the light emission effect of the light-emitting structure. In some other embodiments of the present application, the light-collecting portion can also achieve light collection through structural surfaces of other shapes, thereby improving the brightness of the light-emitting structure, and the present application does not impose any specific restrictions on this.

[0042] In some embodiments, the anti-dispersion portion 111 provided in the embodiments of the present application can achieve the function of light mixing optimization through optical patterns. Figure 4 As shown, it is a structural schematic diagram of another light-emitting structure provided by an embodiment of the present application, wherein, at the light incident surface 110 of the inner lens 100 provided by the embodiment of the present application, the anti-dispersion portion 111 includes a plurality of optical teeth arranged along the first direction; the optical teeth extend along the second direction Y, wherein the first direction X and the second direction Y intersect in a plane perpendicular to the direction from the light incident surface 110 of the inner lens 100 to its light emitting surface (not shown). The first direction X and the second direction Y are optionally perpendicular. Continue as Figure 4As shown, in case that the dispersion-preventing portion 111 includes two sub-dispersion-preventing portions, the dispersion-preventing portion 111 provided by the embodiments of the present application includes a first sub-dispersion-preventing portion 1111 and a second sub-dispersion-preventing portion 1112 located on both sides of the light-incident portion 112, each of the first sub-dispersion-preventing portion 1111 and the second sub-dispersion-preventing portion 1112 includes a plurality of optical teeth arranged along the first direction, and the optical teeth have a strip shape extending along the second direction Y. In addition, the dispersion-preventing portion 111 provided by the embodiments of the present application can also include a plurality of optical teeth. Figures 1 to 3 As shown, the drawings all show that the dispersion-preventing portion 111 provided by the embodiments of the present application can include a plurality of optical teeth.

[0043] When the dispersion-preventing portion 111 provided by the embodiments of the present application includes a plurality of optical teeth, all the light-emitting elements 210 of the light source 200 provided by the embodiments of the present application are arranged in a linear shape along the second direction, and all the light-emitting elements 210 are arranged opposite to the light-incident portion 112. In combination with Figure 2 and Figure 5 As shown, Figure 5 For Figure 2 the section view along the AA' direction, in the light source 200 provided by the embodiments of the present application, the at least two light-emitting elements 210 are arranged in a linear shape along the second direction Y, that is, all the light-emitting elements 210 are arranged in a straight line extending along the second direction Y. It can be seen that, when the dispersion-preventing portion 111 provided by the embodiments of the present application includes a plurality of optical teeth arranged along the first direction X and the optical teeth have a strip shape extending along the second direction Y, arranging all the light-emitting elements 210 in a linear shape along the second direction Y can improve the light mixing effect and the light color uniformity of the light-emitting structure.

[0044] In some embodiments, the light source 200 provided by the embodiments of the present application can include at least two kinds of light-emitting elements of three primary colors, that is, the light source 200 provided by the embodiments of the present application can include at least two kinds of light-emitting elements 210 of red light-emitting elements, blue light-emitting elements and green light-emitting elements. As shown, Figure 5 As shown, the light source 200 provided by the embodiments of the present application includes green light-emitting elements 211, red light-emitting elements 212 and blue light-emitting elements 213, the green light-emitting elements 211, the red light-emitting elements 212 and the blue light-emitting elements 213 are arranged in a linear shape along the second direction Y, and the green light-emitting elements 211, the red light-emitting elements 212 and the blue light-emitting elements 213 are arranged opposite to the light-incident portion 112 of the inner lens 100. In addition, Figure 5 As shown in the light-emitting structure, the dispersion-preventing portion 111 of the inner lens 100 can include a first sub-dispersion-preventing portion 1111 and a second sub-dispersion-preventing portion 1112 located on both sides of the light-incident portion 112, each of the first sub-dispersion-preventing portion 1111 and the second sub-dispersion-preventing portion 1112 includes a plurality of optical teeth arranged along the first direction, and the optical teeth have a strip shape extending along the second direction Y. In addition, Figure 5In the light emitting structure shown, the light incident portion 112 of the inner lens 100 may be a light collecting portion. Figure 5 The light emitting structure shown in the figure is simulated to obtain the following Figure 6 The simulation effect diagram shown is Figure 6 The simulation effect shown is based on the simulation of mixing the green light emitting element 211, the red light emitting element 212 and the blue light emitting element 213. Figure 7 As shown in the simulation effect diagram of an existing light-emitting structure including red, green and blue primary color light-emitting elements, it can be seen that the light-emitting structure provided by the embodiment of the present application has higher light mixing effect and light color uniformity, which improves the light dispersion problem of the existing light-emitting structure.

[0045] In some embodiments, the light-emitting element 210 provided in the embodiments of the present application may be a light-emitting diode. Light-emitting diodes have advantages such as small size, low power consumption, long service life, high brightness, low heat generation, environmental friendliness, and durability. The light-emitting structure provided in the embodiments of the present application uses light-emitting diodes to form the light source 200, which can further improve the light output effect of the light-emitting structure. In addition, in other embodiments, the light-emitting element 210 provided in the embodiments of the present application may also be of other types, and this application does not impose specific limitations on this.

[0046] Based on the same inventive concept, the embodiment of the present application further provides a light emitting device, which includes the light emitting structure provided by any of the above embodiments. Figure 1 As shown, the light-emitting structure includes: an inner lens 100, wherein the light incident surface 110 of the inner lens 100 includes an anti-dispersion portion 111 and a light incident portion 112 arranged in a first direction X. A light source 200 is disposed on one side of the light incident surface 110 of the inner lens 100, and the light source 200 is disposed opposite the light incident portion 112; wherein the light source 200 includes at least two light-emitting elements 210, the light-emitting elements 210 are disposed opposite the light incident portion 112, and the light color of at least one of the light-emitting elements 210 is different from the light colors of the remaining light-emitting elements 210.

[0047] In some embodiments, the light-emitting device provided in the embodiments of the present application can be used in a vehicle. It can be specifically used in the vehicle's lighting lamps, or in the vehicle's signal lights, or can also be used in the vehicle's display components. This application does not impose specific restrictions on this.

[0048] It can be understood that, in the light source 200 provided by the embodiments of the present application, each light emitting element 210 can be controlled to be lit up individually when the light source 200 is controlled to emit light; or part of the light emitting elements 210 can also be controlled to be lit up simultaneously, wherein the light emitting colors of the light emitting elements 210 that are controlled to be lit up simultaneously can be the same, or at least one of the light emitting colors of the light emitting elements 210 that are controlled to be lit up simultaneously can be different from the light emitting colors of the remaining light emitting elements 210; or all the light emitting elements 210 can be controlled to be lit up simultaneously, and the present application does not make a specific limitation on the light-up control mode. In some embodiments, when the light emitting structure is controlled to emit mixed light, part of the light emitting elements 210 with different light emitting colors can be controlled to emit light to the inner lens 100, or all the light emitting elements 210 can be controlled to emit light to the inner lens 100. Since the light entrance surface 110 of the inner lens 100 provided by the embodiments of the present application is provided with the anti-dispersion part 111, the dispersion problem of the different color light emitted by the light source 200 when passing through the inner lens 100 can be improved by the anti-dispersion part 111, the mixed light effect of the light emitting structure is improved, and the light color uniformity of the light emitting structure is improved. In other embodiments, when the light emitting structure is controlled to emit monochromatic light, one light emitting element 210 of the light source 200 is controlled to be lit up, or at least part of the light emitting elements 210 with the same light emitting color in the light source 200 are controlled to be lit up, and when the light with the same color enters the inner lens 100 through the light entrance surface 110, the light can be uniformly processed by the anti-dispersion part 111, so that the light color uniformity of the light emitting structure is high.

[0049] It can be understood that, in the light source 200 provided by the embodiments of the present application, each light emitting element 210 can be controlled to be lit up individually when the light source 200 is controlled to emit light; or part of the light emitting elements 210 can also be controlled to be lit up simultaneously, wherein the light emitting colors of the light emitting elements 210 that are controlled to be lit up simultaneously can be the same, or at least one of the light emitting colors of the light emitting elements 210 that are controlled to be lit up simultaneously can be different from the light emitting colors of the remaining light emitting elements 210; or all the light emitting elements 210 can be controlled to be lit up simultaneously, and the present application does not make a specific limitation on the light-up control mode. In some embodiments, when the light emitting structure is controlled to emit mixed light, part of the light emitting elements 210 with different light emitting colors can be controlled to emit light to the inner lens 100, or all the light emitting elements 210 can be controlled to emit light to the inner lens 100. Since the light entrance surface 110 of the inner lens 100 provided by the embodiments of the present application is provided with the anti-dispersion part 111, the dispersion problem of the different color light emitted by the light source 200 when passing through the inner lens 100 can be improved by the anti-dispersion part 111, the mixed light effect of the light emitting structure is improved, and the light color uniformity of the light emitting structure is improved. In other embodiments, when the light emitting structure is controlled to emit monochromatic light, one light emitting element 210 of the light source 200 is controlled to be lit up, or at least part of the light emitting elements 210 with the same light emitting color in the light source 200 are controlled to be lit up, and when the light with the same color enters the inner lens 100 through the light entrance surface 110, the light can be uniformly processed by the anti-dispersion part 111, so that the light color uniformity of the light emitting structure is high.

[0050] In some embodiments, the anti-dispersion part 111 provided by the embodiments of the present application can be arranged together and located on the same side of the light entrance part 112; continue to take the light emitting structure 1000 shown in FIG. 6 as an example, the anti-dispersion part 111 can be arranged together and located on the same side of the light entrance part 112. Figure 1As shown, the anti-dispersion part 111 is located on the same side of the light-incident part 112 in the first direction X. Alternatively, in combination with Figure 2 As shown, the anti-dispersion part 111 provided by the embodiment of the present application includes a first sub-anti-dispersion part 1111 and a second sub-anti-dispersion part 1112; in the first direction X, the first sub-anti-dispersion part 1111 and the second sub-anti-dispersion part 1112 are respectively located on both sides of the light-incident part 112. As can be seen, when the light-emitting structure needs to realize mixed light emission, the light-emitting elements 210 of different light-emitting colors of the light source 200 are controlled to be lit, the light emission of the light-emitting elements 210 enters the interior of the inner lens 100 through the light-incident part 112 and the anti-dispersion part 111, and when entering the interior of the inner lens 100 through the anti-dispersion part 111, the light of different colors is optimized and mixed to ensure that the mixed light effect of the light emission of the inner lens 100 is high, the mixed light effect of the light emission of the light-emitting structure is improved, and the light color uniformity of the light emission of the light-emitting structure is improved. In addition, when the light-emitting structure realizes single-color light emission, the light of the same color emitted by the light source 200 enters the inner lens 100 through the light-incident surface 110, and the light is uniformly processed through the anti-dispersion part 111 to ensure that the light color uniformity of the light emission of the light-emitting structure is high.

[0051] Further, the light-incident part 112 of the inner lens 100 provided by the embodiment of the present application can be a light collecting structure surface. As shown in Figure 3 As shown, the light-incident part 112 provided by the embodiment of the present application is a light collecting part. The light-incident part 112 can be a convex surface, and when the light emitted by the light source 200 irradiates to the convex surface, the light can be collected and then transmitted to the interior of the inner lens 100, thereby improving the light emission brightness of the inner lens 100 on the basis of ensuring that the mixed light effect of the light emission of the inner lens 100 is high and the light color uniformity is high, thereby improving the light emission effect of the light-emitting structure. In some other embodiments of the present application, the light collecting part can also be realized by a light collecting structure surface of other shapes to improve the light emission brightness of the light-emitting structure, and the present application does not make specific limitations in this regard.

[0052] In some embodiments, the anti-dispersion part 111 provided by the embodiment of the present application can realize the function of mixed light optimization through optical patterns.
